The objective of the present invention is to provide a system and a method for providing customized lighting control information, capable of providing optimum lighting control information to allow a lighting control system to efficiently manage lighting devices in an optimum lighting environment, separately from the lighting control system for controlling lighting devices located in a building or indoor space. To achieve the objective, the system for providing customized lighting control information based on cloud computing comprises: a lighting control information searching unit to input lighting device information and space structure information of a lighting system to be transmitted to a lighting control information managing server, and receive lighting control information and predicted control result information outputted from the lighting control information managing server to be provided for the lighting system; and the lighting control information managing server to generate a set of combinable lighting space information by using space design information and the lighting device information, calculate optimum lighting control information according to the generated lighting space information, calculate the lighting control information and the predicted control result information according to the result of comparing the space structure information and the lighting device information transmitted from the lighting control information searching unit with the stored space design information, and output the lighting control information and the predicted control result information to the lighting control information searching unit. Therefore, the system and the method of the present invention provide the customized lighting control information optimized for the lighting system, thereby allowing the lighting system to efficiently manage lighting devices in the optimum lighting environment and reducing energy consumption by the optimum control thereof.
